Need to edit 3000 PDF files fast.

I have about 3000 pdf files to edit.

The files are each 18 pages long and the last two pages of every file contains confidential information which must be removed after 1 year.

The files have sequential hex codes for file names, so the first, oldest, file is called 00000001.pdf, the 15th file is called 0000000f.pdf, etc.

I need a program, tool, script, macro or any other automated process that will remove the last two pages from every pdf file in the directory.
